Abstract:
This invention relates to a compound for an organic electroluminescent device and to an organic electroluminescent device including the same. This compound for an organic electroluminescent device including the same is improved in thermal stability and light emission efficiency. When this compound is used as a hole transport layer material, a triplet energy of a phosphorescent light emitting material is increased, thus improving the efficiency of the organic electroluminescent device.
